Founding Engineer - Internship

About Us

👋 Hey there. We're Cory and Adon, co-founders of Lume Security. Between us, we've spent 30+ years in security and AI at Google, Microsoft, IBM, and a handful of startups. We started Lume because we've lived the problem firsthand and believe security teams are too good to be this buried.

Security backlog is the attack surface. Those mundane tasks that keep getting deferred quietly compound — access reviews that slip, compliance evidence collection, updating procedure docs, onboarding cycles that drag, abandoned accounts that linger — until they show up at the center of an incident investigation.

AI hasn't fixed this. It made it worse. The copilot got faster. The task backlog got longer. The human is still the bottleneck.

Lume is different. We capture how your organization actually operates — its policies, its people, its institutional knowledge — and put it to work. AI agents embedded in the tools security teams already use automate entire categories of work. The agents get stuff done so the human can focus on what they’re great at - thinking creatively and exercising judgement.

We just came out of stealth. We’re building with customers. We raised our first round. Now we need you to keep up with demand.

What you'll work on

You'll work at the intersection of graph intelligence, agentic automation, and real customer problems. Some days are planned. Others start with a customer call and end with a working prototype.

• Contribute to the intelligence graph. Help capture how organizations actually make decisions — mapping policies, approvals, exceptions, and institutional knowledge. The manual work exists because this context is missing. You'll help make it findable and actionable.
• Build and ship agentic workflows. Our agents don't follow static playbooks — they reason through organizational context and construct the right approach on the fly. You'll build and test the workflows that make autonomous action possible, safe, and useful.
• Experiment fast. When something surfaces from a customer conversation, we turn it into a working experiment before the next meeting. You'll contribute to that loop — insight to demo in hours, not weeks.
• Stay ahead of the frontier. Graph theory, context engineering, agentic orchestration — you'll track what's actually moving the needle and bring ideas from the field into what we're building.

What you bring

• You've built agents or multi-step LLM workflows — hackathon projects, side projects, class projects. You have opinions about what breaks, why it breaks, and what a better design looks like.
• You have a point of view on agentic UX. Autonomous agents that act without clear user control are a UX failure. You think carefully about how humans and agents should share decision-making — what to surface, what to hide, when to confirm, and when to just act. You've probably argued about this with someone.
• You think in systems. When someone describes a workflow, you're already modeling the graph.
• You build fast and rough-draft well. You're not waiting for a perfect spec. You'd rather show something broken than describe something perfect.
• Proficient in Python and/or TypeScript. With and without AI coding support — you understand how to critically assess good coding practice.

Bonus: You’ve worked in or near security. Capture the flag, security coursework, bug bounty, internship in IT/security ops. You know what it looks like when something goes wrong and have thought about why.

Top qualification: You've shipped something agentic — even small, even half-broken — and can clearly articulate what you'd do differently. Strong opinions, genuine curiosity, and the ability to learn quickly.

Why join

• Ship real code with real customers — not intern busywork.
• Be an early contributor to the intelligence layer for enterprise security — a category that's just getting started.
• Work directly with the founders. You'll be in the room when decisions get made.
• If you have an idea, run with it. We're here to lift you up, not get in your way.
• Paid internship with real potential for a full-time Founding Engineer offer.
